Marshall's acquisition was barely being digested in Chicago and Miami when reports emerged late Tuesday that the often-troubled receiver was allegedly involved in a melee at a New York nightclub over the weekend. The New York Post reported that a woman told police that Marshall struck her in the face. Marshall's attorney released a statement alleging that Marshall was trying to take his wife to the hospital after she was hit in the face by a bottle. It wasn't clear whether or not the Bears knew of the incident when they agreed to the trade.

Marshall was shipped to the Dolphins from the Broncos on April 14, 2010 for second-round picks in the 2010 and 2011 drafts. The Broncos used their 2010 pick as part of a package in a draft-day trade with the Baltimore Ravens in order to move up and select quarterback Tim Tebow with the 25th overall selection.

Playing with quarterback Chad Henne and Matt Moore, Marshall made the Pro Bowl after finishing the 2011 season with 81 catches for 1,214 yards with six touchdowns. The Bears' leading receiver this past season was Johnny Knox with 37 receptions for 727 yards and two touchdowns.
